PU LVERIZER.

SPECIFICATION forming part of Letters Patent No. 517,138, dated March 27, 1894.

Application iiled March 18, 1893. Renewed February 27,1894 Serial No. 501,737- (NO model-l .To a/ZZ whom it may concern:

Beit known that I, ADAM FIsCUs, a citizen of the United States, residing at Fiscus, in the county of Audubon, State of Iowa, have invented certain new and useful Improvements in Pulverizers; and I do declare the following to be a full, clear, and exact description of the invention,such as willenable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to harrows and .pulverizers.

The improvements consist in the following construction of parts, the features of which will first be fully described and the points of novelty therein contained then set forth and claimed.

In the drawings-Figure l represents a perspective view looking at the front of a machine. Fig. 2 is also aperspective view looking at the machine from the rear.

A represents the head-bar of the machine. B are the teeth secured in transverse slits therein.

C is a transverse rod passing through 'holes in the front end of the teeth in front of the head A and serving to hold the teeth in place thereon. It will be noticed that the teeth or knives B are curved outwardly in both directions from the center.

D are the wheel-axles, one for each wheel, mounted upon the tooth-head bar A so as to oscillate thereon. The outer ends of these axles are cranked--upon which the main wheels E are journaled. The opposite or inner ends of the axles D are similarly provided with crank-arms F, to which are pivotally connected connecting-rods G, which lead to levers H journaled upon the rear of the machine-and provided with a rack and dogmechanism-by means of which the pulverizer-frame is raised or lowered and adj ustably set at any desired height from the ground.

I are two rearwardly extending frame-bars projecting from the head of the pulverizer, to the rear ends of which is secured a smoothing or crushing bar J. To these bars I are also secured the rack and lever mechanisms for adjusting the axles.

K is a spring-seat mounted' directly upon the smoothing-bar J. l

L is the pole, and M is a strap-piece upon the frame crossing the inner end of the pole, for limiting the movement of the tongue.

N is a cross-bar uniting the bars I and the hounds of the tongue, and serving to strengthen and give greater rigidity to the machine. O is another cross-bar secured to the under side ot tne bars I and slitted so as to guide and maintain the position of the knives or teeth B. Another cross-bar P is employed beneath the tooth orknife-head A, which is employed for a purpose similar to the bar O-the former acting to hold the teeth up to their position and the latter down to the same.

The knivesorteeth of themachinethoroughly stir up and cultivate or harrow the soil, while the succeeding dragging and crushing force of the drag-board completely comminutes the soil.

A series of drag-boards may be used if desired, presentinga seriesof upwardlyinclined planes toward the front of the machine.

In Figs. 3 and 4 are shown respectively a perspective and plan view of a modified form of my invention. In this modification I employ a series of smoothing-boards G to one of which I may secure axles or handles J.`

The seat H runs fore and aft and is attached in front to a cross-bar I and at the rear to one of the smoothing-boards G.

I claim- The combination in a pulverizer or harrow,

of the head-bar having the curved teeth mounted thereon, crank axles secured thereto, levers attached to the inner ends of the crank axles, a smoothing or crushing frame in rear of the head-bar, frame bars secured to the head-bar and extending rearwardly to support the smoothing frame, a rack and lever mounted upon each of said rearwardly extending frame-bars, and links connecting the said levers and the levers attached to the inner ends of the crank axles.

In testimony whereof I affix my signature in presence of two witnesses.
